Methionine transaminase
Methionine transaminase (EC 2.6.1.88, methionine-oxo-acid transaminase) is an enzyme with systematic name L-methionine:2-oxo-acid aminotransferase.[1][2][3] This enzyme catalyses the following chemical reaction
- L-methionine + 2-oxo carboxylate 2-oxo-4-methylthiobutanoate + L-amino acid
